利用新提出的Gilmore-NASG模型, 在考虑液体可压缩效应的边界条件下, 研究了可压缩液体中气泡的声空化特性, 并与利用原有KM-VdW模型计算得到的结果进行了比较. 结果表明, 相比于KM-VdW模型, 由于Gilmore-NASG模型采用新的状态方程来描述气体、液体以及由可压缩性引起的液体密度变化及声速变化, 所以用Gilmore-NASG模型得到的空化气泡的压缩比更大、崩溃深度更深、温度和压力峰值更高. 随着驱动声压幅值的增大, 两种模型给出的结果差别愈加明显, 而随着驱动频率的增大, 两种模型给出的结果差别逐渐减小. 这表明, 在充分考虑泡内气体、周围液体在不同温度和压强下共体积的变化所导致的介质可压缩特性下, 气泡内的温度和压强可能达到更高值. 同时, Gilmore-NASG模型还预测出了气泡壁处液体的密度变化、压力变化、温度变化以及液体中的声速变化. 因此, Gilmore-NASG模型在研究高压状态下气泡的空化特性以及周围液体对气泡空化特性的影响方面具有优点.The newly proposed Gilmore-NASG model is used to study the acoustic cavitation characteristics of bubble in compressible liquid under the boundary condition of considering the compressible effect of the liquid, and comparison is made between the results calculated by the Gilmore-NASG model and original KM-VdW model without considering the mass exchange, chemical reaction and heat exchange between the gas in the bubble and the surrounding liquid. The results suggest that, compared with the KM-VdW model, the Gilmore-NASG model which employs a new equation of state to describe the gas, liquid and variations of liquid density and sound velocity due to compressibility, can give a larger compression ratio of cavitation bubble, a deeper collapse depth, higher temperature and pressure peaks. This is mainly because that the co-volume of argon molecule in the NASG equation of state is smaller than that in the VdW equation of state and the effect of the co-volume of water molecule is considered in the NASG equation of state, that is, the Gilmore-NASG model gives more comprehensive consideration to the liquid compressibility. When the bubble collapses violently, the Gilmore-NASG model takes into account the changes of sound velocity caused by the compressibility of the liquid at the bubble wall, effectively avoid the possibility of abnormal increase in the Mach number of the liquid at the bubble wall. With the increase in the driving sound pressure amplitude, the difference between the results given by the two models more and more significantly and the temperature and pressure peaks in the bubble given by the Gilmore-NASG model increase more significantly. With the rise of driving frequency, the difference between the results given by the two models gradually decreases and tends to be consistent under the high-frequency excitation. This indicates that the temperature and pressure in the bubble may arrive at higher values considering the compressibility of the medium caused by the co-volume changes of gas and surrounding liquid at different temperatures and pressures. In the meantime, the Gilmore-NASG model can accurately predict the changes in density, pressure and temperature of the liquid at the bubble wall as well as sound velocity, so this model has advantages in the study of bubble cavitation characteristics under high pressure and the effect of surrounding liquid on bubble cavitation characteristics. There will be important applications for the research on specific issues such as high-intensity focused ultrasound, shock wave lithotripsy treatment and sonochemistry.
